BLR's are IMO classy rifles! I have held and fired one, but have never owned one.
With only one bullet weight commercially I would consider reloading. Do you have a buddy who reloads? If so you could get away with just the price of dies and powder, primer, brass and bullets.
I own and shoot some rifles with very expensive ammunition, if you can find some. 300WBY,340WBY, 6.5-284, amoung others. So reloading is neccessary if I want to shoot as much as I like.
I wouldn't be satisfied with two bullet options. Good luck and good shooting.
